Everybody is talking climate change, storms are increasing, weather fluctuations increasing and no trace of ETS anywhere.
Meanwhile large companies GHG emissions going up instead of down (http://www.environmentalleader.com) and so do NZ GHG emissions (http://www.scoop.co.nz)
On the other hand, private companies like my employer Babbage Consultants have signed up to carboNZero, a GHG emission accounting, reporting and offsetting scheme, with more companies having joined since, like Brother International. Good on you Brother.
It would appear that you can spend a lot of time waiting for governments to move.
Check out the carboNZero website. Worth a look at what company is taking Climate Change and GHG emissions seriously.
